Which 42" LG is better 42LD550 or 42LM3700?

[Pioneerx01]

I repair TV's on the side, and right now I have two fully functional 1080p 42" LG TV's. Both have their good and bad features. Here are the critical specs for each:

42LD550
4.5 years old (-)
150,000:1 DCR (-)
120Hz (+)
LCD panel (-)
Network capable + wireless (+)
Not 3D (-)
4x HDMI, 2x composite, 2x component, 2x USB, headphones and optical (-)

42LM3700
2.5 years old (+)
3,000,000:1 DCR (+)
60Hz (-)
LED Panel (+)
No network capability (-)
3D (+)
2x HDMI, 0x composite, 1x component, 1x USB, no headphones, optical out (-)

I do not watch 3D and the network content on the other one is limited (useless). I like the 120Hz, but I also like the 3M:1 DCR and LED panel with extra ports. I will watch movies on it so bout 120Hz and LED with 3M:1 DCR would be nice, but they are not on same TV.

I feel that 42LD550, even though older, is better TV. Thought, suggestions?

Thanks

you do know that led is the backlight.
and that many failures are occuring.
so much for the claimed lifespan!
it may be ok but the old ccfl backlight is mature tech.
the newer set is a better seller.
